bluntly rounded. The surface is rather smooth and 

 shining below, but above is minutely roughened, espec- 

 ially so on the head and thorax where it becomes 

 opaque. On each side of the abdomen are three 

 rather large slits on as many body divisions, 

 and on each side near the front end is an- 

 other similar opening. They resemble large breath- 

 ing pores, but cannot have to do with respiration be- 

 cause true pores (spiracles) occur on the segments of the 

 body bearing the clefts. 



The adult is one of the hawk-moths such as are seen 

 about flowers of summer evenings . The catalpa moth 

 is more retiring than others of its family, and has never 

 been captured us far as I know about flower beds. I 

 have not myself secured any examples except those 

 carried through their changes in boxes. They are dull 

 brownish gray in color with obscure lines and spots of 

 black. The more noticeable marks on the wings are : 

 A spot on the front margin of the fore wing about a third 

 the distance from the base to the apex ; from it a line ex- 

 tends obliquely across the wing and parallel and within 

 the latter is another narrow line. The disk of the wing 

 is uniformily brown excepting for a whitish dot encircled 

 with black. The outer third of the fore wing has a 

 number of zig-zag black lines extending across it, and 

 a distinct black dash running from the apex obliquely 

 inward. The hind wings show only two very obscure 

 cross bands. The fringes are black, broken at intervals 

 with white. The sides of the head and thorax are dark, 

 brownish black. Above this the color is light gray, then 

 come the black lines of the thorax separating the light 

 gray from the brownish gray of the middle part of the 

 thorax. The abdomen presents three distinct long- 

 itudinal lines of black, one median, the others at each 

 side and consisting of a series of contiguous spots. Still
